Abb CR123C630A Overload Heater Element

Product Description

The ABB CR123C630A is a thermal overload heater element designed to protect motors and electrical equipment from overcurrent damage. It installs inside a compatible overload relay assembly, where it generates a calibrated heat response proportional to current draw. When current exceeds the rated threshold, the heater causes the relay to trip, disconnecting the load and preventing motor burnout. Licensed electricians and industrial maintenance technicians are the primary installers of this component in motor control applications.

Thermal overload heater elements like the CR123C630A are used in motor control centers, combination starters, and panel-mounted overload relay assemblies across light commercial and industrial settings. They are sized to match the full-load amperage of the protected motor, making correct selection critical to system protection. This heater element suits applications where precise overcurrent trip response is required within a relay-based motor starter circuit.

Key Features

• Calibrated heater element provides accurate trip response matched to motor full-load amperage
• Designed for installation inside compatible thermal overload relay assemblies
• Compact and lightweight construction at 0.29 pounds for easy handling during installation
• Supports reliable motor protection in commercial and industrial motor control applications

Compatibility

Designed as an OEM-style replacement heater element for use in compatible ABB thermal overload relay assemblies. Consult the relay manufacturer documentation to confirm correct heater sizing for your specific application.

Installation Notes

Installation should be performed by a licensed electrician in accordance with applicable NEC requirements. De-energize and lock out the motor control circuit before removing or installing any overload heater element. Verify that the heater element rating matches the full-load amperage of the motor being protected before placing the assembly back in service.
